Benefits of technology

The solution allows for secure fixation and easy removal of the compressed coil spring, enhancing the usability and efficiency of the spring mechanism in electronic devices by simplifying the installation and removal process.

Problems solved by technology

Further, in the art of the Jpn. Pat. Appln. KOKAI Publication No. 6-313456, since the bent fixing lugs are fixed by bending toward both sides of the wire ring, once the coil spring is fixed, the coil spring cannot be removed without bending back the bent lugs to the original position.

embodiment 1

[0038](Embodiment 1)

[0039]FIGS. 1A and 1B show the structure of a spring mechanism according to a first embodiment of the present invention. FIG. 1A is a side view, and FIG. 1B is a plan viewed from the rear side of the plate member of FIG. 1A.

[0040]In FIGS. 1A and 1B. a compressed coil spring 10 is a spring member formed by deforming a linear elastic member. The compressed coil spring 10 constitutes a negative pole contact of a dry cell (not shown), and has a spring 10b that is a spiral portion continued from a contact 10a, or one end of the spring. The bottom of the spring 10b has a spring seat winding (an end turn of the coil spring 10) consisting of double-wound springs.

[0041]At the bottom of the spring 10b, an extension 10c is formed extended linearly from the bottom. The extension 10c is further extended and formed continuously with a bent portion 10d that is bent substantially perpendicularly to the other end of the compressed coil spring 10, a linear extended portion 10e, a ...

[0067](Embodiment 2)

[0068]A second embodiment of the present invention will be explained.

[0069]FIGS. 3A and 3B show the structure of a spring mechanism according to a second embodiment of the invention. FIG. 3A is a side view, and FIG. 3B is a plan viewed from the rear side of the plate member of FIG. 3A.

[0070]In FIGS. 3A and 3B, a compressed coil spring 18 is a spring member formed by deforming a linear elastic member. The coil spring constitutes a negative pole contact of a dry cell (not shown), and has a spring 18b that is a spiral portion continued from a contact 18a, or one end of the spring. The bottom of the spring 18b has a spring seat winding consisting of double-wound springs.

[0071]At the bottom of the spring 18b, an extension 18c is formed extended linearly from the bottom. The extension 18c is further extended and formed continuously with a bent portion 18d that is bent substantially perpendicular to the other end of the compressed coil spring 18, and a linear extended p...

embodiment 3

[0080](Embodiment 3)

[0081]A third embodiment of the present invention will be explained.

[0082]FIGS. 4A to 4C show the structure of a spring mechanism according to a third embodiment of the invention. FIG. 4A is an outside perspective, FIG. 4B is a side view, and FIG. 4C is an elevation showing the structure of a compressed coil spring.

[0083]In FIGS. 4A to 4C, a compressed coil spring 22 is a spring member formed by deforming a linear elastic member. In the third embodiment, the engagement part and spring of the compressed coil spring 22 are arranged on the same side of a plate member.

[0084]The compressed coil spring 22 has a spring 22b that is a spiral portion continued from a contact 22a, or one end of the spring. The bottom of the spring 22b has a spring seat winding consisting of a double-wound springs.

[0085]At the bottom of the spring 22b, an extension 22c is extended linearly from the bottom. The extension 22c is further extended and formed continuously with bent portions 22d a...

Abstract

In a cell cover according to the present invention, a compressed coil spring formed by deforming a linear elastic member is fixed to a plate member provided with a raised bent portion as a projection on a first side. The raised bent portion engages with an engagement part comprising a plurality of extended portions and bent portions of the compressed coil. A spring of the compressed coil is formed on a second side of the plate member. A spring seat winding at the bottom of the spring is pressed to the end face of the plate member.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2003-195863, filed Jul. 11, 2003, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a spring mechanism for fixing a compressed coil spring to contact a dry cell, for example, and a cell contact mechanism for small electronic devices.[0004]2. Description of the Related Art[0005]Conventionally, in a cell housing of an electronic device, for example, a spring mechanism is used as a terminal plate to contact the cathode side of the cell. In the spring mechanism, a claw for fixing the compressed coil spring constituting the spring mechanism is formed at a predetermined position on the terminal plate in the cell housing.[0006]The spring mechanism is formed as described in Jpn. Pat. Appln. KOKAI Publication No. 6-313456, for ex...
